Karhu Fulcrum Technology

The Fulcrum Improves Efficiency

Our patented fulcrum technology collaborates with the foot to convert a runner’s energy into efficient forward momentum.

The newest Karhu fulcrum utilizes advanced design and composite materials to create lightweight strength and responsiveness.

Less Wasted Energy

Lower vertical oscillation results in more efficient forward momentum.

Better Body Positioning

Better foot and leg positioning means reduced braking forces and smoother heel-to-toe transition.

• Lower vertical oscillation means less time to overstride
• Better leg and foot positioning creates less braking forces
• Continuous forward momentum requires less effort to maintain running velocity
• Consistent running velocity results in more efficient stride

Less Pronation

Reduced pronation angle and velocity due to naturally centered movement over the fulcrum.

Reduces Chances for Injury

Pressure mapping shows Karhu footwear moves quickly off the heel while push off forces one direction... forward. This improves balance and reduces chances for injury. Check out this video to learn more.

Lower your pronation angle and velocity

Karhu footwear is engineered for total biomechanical efficiency, which translates to less wasted energy. Pronation, or the inward roll of your foot, is essentially wasted energy because you want to be moving forward, not side to side. Karhu shoes help to reduce the angle of pronation as well as the speed at which you pronate to keep you moving forward. Check out this video to learn more.

Independently Tested and Proven
At University of Jyväskylä

Don't know how to pronounce Jyväskylä? No problem! You can just refer to it as "the best running footwear research facility in the world." Watch the video to learn more and see Karhu research in action.

Less vertical oscillation

Moving forward sounds simple, right? Well, if you're wearing Karhu footwear it is. Our patented fulcrum technology helps convert your body's natural energy into forward momentum. Watch the video to learn how Karhu footwear can help you get the most out of your run.
